  • I would slap them upside the head just for that!

    • It'd be more useful too slap the people specifying /bin/sh in their shell scripts that rely on features of bash.
  • on a Debian based system line Ubuntu it should also be possible to revert the upgrade to bin/perl itself, reinstalling the older 5.8
    8 as bin/perl with the Debs, and pinning that version. this may rollback and block an expanding number of dependant upgrades, however.

    as is stated elsewhere, having app prod perl be OS bin/perl is dangerous, best to have your own.

    # I had a sig when sigs were cool
    use Sig;

      Every time I think about this I am torn. I'm sure most people know the pros and cons of relying on the OS perl install. The big problem that I see is that my operating system provides me with an excellent package manager. A package manager that I have to use anyway, too.

      I've always thought it would be useful to have some standardized disto packages that provide an alternate Perl install.

      Debian and Ubuntu already have a pretty large percentage of the CPAN modules I need rolled up into packages. However,

  • Note to kids finding this on google: don't follow any of these instructions unless you like hosing your system.
    • Can you please be more specific? I do state that people should be setting PREFIX to avoid overwriting the system perl. Should that be highlighted sooner, I suppose. Are there other issues that users should be aware of?

    • Note to kids finding this on google: since this person never came back and bothered to offer any evidence to support their claim, you can probably ignore it. Personally, if there is a problem here, I'd love to know about it, but frankly, my Ubuntu system has been fine since I've done this.

      • Slashdot syndrome: he read the title but not the article. The title makes it sound like you're trying to literally downgrade the system perl, but you of course understand how to use PREFIX to install alternative perls.

        Thanks for writing this up, by the way: I've been trying to build an old perl, and I had pretty much blundered my way through to just before the last fix you have here-- and I was glad to see that you didn't understand where the problem came from either.

  • Hello, I have 64 bit Ubuntu 10.04 LTS. I want to downgrade it from 5.10.1 to 5.8.8. So is it safe to use this method? Thanks.
